Grenade 50 Calibre is a hard hitting, pre-workout detonator designed to make every workout an explosive, energy fuelled session.

Powered by Grenade 50 Calibre combines full potency dosages of research-validated ingredients so as to deliver higher energy levels and better pumps. The 50 Calibre Pre also contains patent pending MDS (Muscle Defence System) support designed to help you to avoid excess muscle breakdown during training.

Who should use .50 Calibre?

Bodybuilders, strength and power athletes and just about anyone who wants to improve their workout performance can benefit from .50 Calibre. Research has indicated that the ingredients in .50 Calibre can increase strength, support the muscle-building process, could boost levels of several muscle-building hormones and increase blood flow, as better blood flow equals bigger, better muscle pumps.

What makes Grenade .50 Calibre better than other Pre-Workout Products?

Containing over 20 University tested ingredients in high-potency dosages, .50 Calibre was formulated by Grenade’s Research and Development team after evaluating and considering every possible natural component that has been studied to enhance physical performance. Grenade .50 Calibre contains large dosage of citrulline malate (a no-boosting amino acid), high-nitrate beta vulgaris, high-dose, flavanol-rich, theobroma cocoa and numerous other effective ingredients that support muscular blood flow.
